Common compounds in the "Western" diet seem to promote Alzheimer's-linked brain deposits and memory problems in mice, researchers say. Scientists found that when they added the compounds -- called advanced glycation end products (AGEs) -- to the lifelong diets of laboratory mice, the animals developed greater amounts of beta-amyloid in the brain. Beta-amyloid is the protein that makes up the brain "plaques" seen in people with Alzheimer's disease.
